In chronic granulomatous disease (CGD), immune system cells called phagocytes are unable to kill some types of bacteria and fungi. This disorder leads to long-term (chronic) and repeated (recurrent) infections. The condition is often discovered very early in childhood.
The 1961 Lincoln Continental Presidential Limousine, in which President John F. Kennedy was assassinated in 1963, was donated to The Henry Ford by Ford Motor Company in 1978. The car, completely rebuilt after the assassination, did not go on exhibit until 1981.
The day JFK was shot his car was moving much slower than the 45 mph minimum dictated by Secret Service protocal. Notice in live footage how the foot patrol agents were called off just before the kill zone. The driver slowed and looked back twice to confirm that the kill was good. THEN he sped up.
